This document defines a technical solution for encrypting resources in digital publications (especially EPUB), effectively registering a device certificate to providers and securely delivering decryption keys to reading systems included in licenses tailored to specific devices. This technical solution uses the passphrase-based authentication method defined in ISO/IEC 23078-2 for reading systems…

This document defines a technical solution for encrypting resources in digital publications (especially EPUB) and for securely delivering decryption keys to reading systems, included in licenses tailored to specific users. It also defines a simple passphrase-based authentication method for reading systems to verify the license and access the encrypted resources of such digital publications.

This document describes three types of copyright protection technologies in use in the publishing industry: —     digital rights management (DRM) free protection, i.e. technologies which do not rely on content encryption but rather use content fingerprinting or watermarking, adequate for use cases where user convenience is the top priority; —     user key-based DRM protection, adequate where user…
